Born in Darkness Part 4

The Skeleton Key is almost ready. The Stranger believes one more boost of energy from combatants near a Crux should do it.
"One final burst of energy, and we'll have what we need to face the Clovis AI together. There's a Fallen Captain that's been making its way towards him. Taking it down should be all you need." —The Exo Stranger
